well, you know how linux distributions work: they ship old tex's while 
users want new macros (no problem since they can update that part in a 
local tree) ; also, there is the "unwilling to update sysadm" problem -)

last night i spent some time on that issue,

i thought about parsing the banner, but then i depend on

- the engine having that name
- the  keeping the same format (or adapt at each new version)

and so i rejected that option;

i decided for this year to use --translate-file=natural.tcx in 
texexec.ini and next year to switch to --8bit

(i hope that live will be more comfortable when the new kpse libraryis 
there and can be accessed as a deamon)
